debug_traceBlockByNumber - Ethereum
The debug_traceBlockByNumber method is part of the Ethereum JSON RPC Core API and is used for advanced debugging. This method provides a full trace of all invoked opcodes for all transactions.
Returns full trace of all invoked opcodes of all transactions includedin the block.
The debug_traceBlockByNumber method is part of the Ethereum JSON RPC Core API and is designed for advanced debugging purposes. This method provides a full trace of all invoked opcodes of all transactions included in a specified block by its number. It is particularly valuable for developers seeking detailed insights into transaction execution at the opcode level.
Supported Networks
The debug_traceBlockByNumber RPC Ethereum method supports all Ethereum network types, including:
Mainnet
Testnets: Sepolia, Holesky
Parameters
The debug_traceBlockByNumber method accepts the following parameters:
quantity|tag: (None) Integer representing a block number or one of the string tags latest, earliest, or pending as described in Block Parameter.
Object: (Object) Request options, all of which are optional and default to false.
Request Example
URL (API Endpoint) https://go.getblock.io/<ACCESS-TOKEN>/
To make a request, send a JSON object with the jsonrpc, method, and params fields. Below is an example of how to make a request using curl:
Response Example
The server responds with a JSON object. Below is an example response for the debug_traceBlockByNumber method:
Response Description
result: null if the method is not allowed or unavailable.
status_code: The HTTP status code for the request.
message: A descriptive message explaining the response, e.g., "Method not allowed."
Returns
If successful, the method provides a detailed trace of all transactions in the block, including:
block: The block details, including its number and transactions.
transaction: A detailed trace of each transaction in the block.
parameters: Opcode-level execution details and associated data.
value: The values used or modified during the transaction execution.
Use Case
The debug_traceBlockByNumber method is critical for developers needing detailed debugging of Ethereum transactions at the opcode level. It aids in analyzing gas consumption, investigating failed transactions, and diagnosing issues in smart contract execution. If a debug_traceBlockByNumber error occurs, ensure the provided block number or tag is correct and that your node supports this method. The provided debug_traceBlockByNumber example demonstrates how to construct a proper request.
Example Code
Here is an example of how to call the debug_traceBlockByNumber method programmatically using Python:
This Python script demonstrates how to interact with the debug_traceBlockByNumber method programmatically. Replace <ACCESS-TOKEN> with your actual API key. The Web3 debug_traceBlockByNumber method can also be used through Web3 libraries for Ethereum, enabling opcode-level transaction analysis and facilitating advanced debugging scenarios for Ethereum smart contracts and transactions.
